A swivel chair consists of a seat mounted on a screw-threaded column in such a way that when the seat is given a clockwise rotation it rises vertically. The seat, of moment of inertia about its rotation axis / and mass M, is given an initial clockwise rotation of angular velocity . How far does the seat rise, assuming no friction?
